Abilitations 89.35 Gymnic Sit'N'Gym Therapy Ball with Built in Legs, 13-1/2 Inches, Clear with Stars

Our B.R.Q. models (Burst Resistance Quality) resist puncture from any source, however in case of a puncture, ball deflates slowly. Active users work on aerobic exercises, stretching, strengthening and relaxation, and classroom students get the same benefits while actively sitting. Virtually every muscle in the core and legs is used. Choose a size by measuring the individual's arm length (arm pit to finger tips) and ordering the closest ball size.
